Going to dive the Red Sea early April, Deadalus and St Johns. Don't seems to see alot of macro pictures from the Red Sea, so what will I miss if I don't bring my macro gears at all?

I'm asking because my smile doesn't work at the check-in counters as magical as some other guys post here, tired of travelling with 40kg luggages, and trying to save couple kg by leaving out the macro port, extension etc., if these's nothing much to lose, or is there?

Just realized I needed a plan for the year when I failed to book tickets for a dive trip next month because of local festival.

I'll have 8 to 12 weeks to spend underwater in the next 12 months. It would be very appreciated if you could share your thoughts on overall planning, such as where and when to go for the best diving destination, so that I can plan well ahead, enjoy some early birds cost savings and most importantly avoid the problem I just had. I'd usually stay with a resort/boat for a week, so I can visit 8 to 12 dive destinations this year if well-planned. So, kindly your recommendations please!

Reputable vendors are also more than welcome to contact me if you're interested in offering an overall package recommendation.

Just come up with the idea, since the 2 looks alike (more or less), and both are good to have for macro, why don't we have them both together?

I'm not good at DIY, but I really hope someone try it out if you like the idea, and I wish I can buy one someday from a housing vendor if it proves to work.

So it will be a sealed collar or ring flash attached to a macro port, with air trapped in, a clear window or 2 on the side(s), so you can point your strobe(s) to the clear window(s). Personally I would point one strobe to it and leave the other strobe where I want it. The air trapped in should help offset the heavy lens/port. there should be an opening somewhere, maybe the face plate of the ring be removeable with o-ring seal, so that you don't seal it permenantly say when you're flying, and you can try install different difusers or gels. The seal is not that critical anyway, the worst case you lose some floatation lift, for the dive.

I have some questions on macro/supermacro with Canon 5D2 in Ikelite housing, really appreciate if you could help shed some light here:

- the new 100mm L lens, worth upgrading from 100macro usm? how do you rate the improvement in scales 1-5, in aspects like optical, AF speed, IS feature good or bad (given that we can't turn it on/off underwater)

- it's a little longer than the old 100macro so I figure it won't fit in the ikelite focus macro port, has someone tried the ike modular ports with this new 100mm L lens? does the ike modular focus ring work with it?

- beyond 1:1, diopter: the ike 100macro focus port is so tight there's simply no room for any dry diopter, with modular port system dry diopter should be possible, could you pls share your favorate diopter with canon 100mm?

- what are some 3rd party wet diopter options available to ike ports? experience?
